Abstract : Injuries are the most serious health problem facing women in the military today. The overall goal of this study is to provide a comprehensive understanding of injuries to women in the military and to develop the basis for effective means to prevent specific injury problems. This study will begin with an analysis of data for serious injury (deaths and hospitalizations) in collaboration with Army, and later Navy investigators. Our work will expand the scope of their earlier studies and will then include injuries to women in the Air Force. In addition, a series of in-depth analytical studies will address specific injury problems in women (injuries related to alcohol, pregnancy, sports, training, etc.), using the ability to link records both within a single database and across different sources of data. Drawing on our extensive experience analyzing injuries in civilian databases, this study is the first in-depth analysis of injuries to women in the military and will combine denominator data with numerator data from hospitalizations, fatalities, and lost-time injuries. These analyses will provide a better understanding of the unique injury hazards to women in the military and will form the basis for the development of sound prevention policies.
